Geometric deformation of dimple as a function of vacuum tip diameter.
(a) Cross-sectional profiles of local dimple versus position for five different diameters of vacuum tips. (b) Measured positive/negative bending radii and slope angles of dimple structures as a function of tip diameter. Red, blue and black lines indicate the positive bending radius, negative bending radius and slope angle, respectively. (c) The variation in εdist as a function of tip diameter.
